[vtkusers] ??? surface mesh and determination of in/out of the volume

[Michael Hilbinger]

Hello,

I want to use vtk to construct layer meshes from a given surface mesh
defining a volume and - as expected - I'm encountering problems.

how could I solve the following:

I have a surface mesh consisting of triangles. As said, the surface is
closed and will represent a volume. If I want to contruct an offset surface
mesh inside the original surface mesh by geometrical definition, I'll need
to determine the direction towards the inside of the volume. Has anybody an
idea how I might perform this task?

Best regards
Michael
